Take it slow Conan and do your research, joining a religion is like dating. When you go out on dates with someone they usually act great and you see only the best side of the person all the flause in the person they don't want you to see it only after you have been with the person a long time even after getting married until the bad side of the person comes out. Would it not be great to see all sides of the person before you committed to them so you new what you we're getting into.
So again do your research, the people your studying with will only present the good side and may not even know about the other side but you can find out so as to make the right decision for you.
